Sandbox test space

Now you have the ability to safely run apps and open files you’re unsure about

Yes, your PC can run it

If your PC can run the full version of Windows 7, it can run Internet Security. Period. But if you’re buying it for someone else, you may still want to check the system requirements.

System Requirements

You need at least Windows XP (with SP2) installed. Windows Vista, 7, 8, and even 8.1 are fully supported (unless your device runs the Starter or RT edition) in both the 32- and 64-bit variant. A 10-year old Pentium 3 processor will do, with 128 MB RAM and 2 GB of hard-drive space. And now imagine the stellar performance with your new hardware!

There’s security in numbers

More people around the world trust Avast for their security than any other company. That means better security for all of us. The reason is simple: We see and react to more data from more users, so we can make your protection better.
